This document describes an analytical procedure for the determination of main components in Li composite oxides for Li-ion batteries (LiB).
These are in particular the elements:
Lithium, cobalt, iron, manganese, nickel, phosphorus, titanium and aluminium, depending on the composite oxide of interest.
The determination is applicable to all types of LiBs (table 1). The determination is performed by optical emission spectrometry with inductively coupled plasma (ICP OES) using an internal standard. The method of atomic emission spectrometry with inductively coupled plasma (ICP AES) is interchangeable with ICP OES.
This test is recommended as the preferred method for determining the stoichiometric composition of several elements in LiBs. This standard establishes a test procedure for a high precision determination of stoichiometric composition of the elements in LiBs.
Please refer to draft for Table 1 — Types of Li composite oxides for LiBs
